Abstract

This mechanism provides a structure for incrementing a signal source and a signal receiver in unison across a document path. The source and receiver are aligned adjacent opposite surfaces of a document located in the document path.

Incrementing Mechanism

This mechanism provides a structure for incrementing a signal source and a signal receiver in unison across a document path. The source and receiver are aligned adjacent opposite surfaces of a document located in the document path.

In drawing B, upper carrier 2 is journaled about shaft 3 and lower carrier 4 is journaled about shaft 5 with a document path, which passes through slot 7 in frame 8, vertically defined between them. Carriers 2 and 4 support the source and sensing elements. Upper belt 10 is trained over driving pulley 11 and idler pulley 12 with clevis 13 secured to the upper stretch of belt 10 which confines carrier 2 and controls its longitudinal movement along rod 3. Carrier 2, drawing A, has detent 14 mounted on it which engages the teeth of rack 15 carried by frame
8. Clevis 13 loosely confines carrier 2 such that, when belt 10 is driven, clevis 13 moves carrier 2 approximately from one detented position to the next. The looseness between clevis 13 and carrier 2 allows the carrier to position itself by detent 14.

In like manner, clevis 18, secured to the lower stretch of belt 19 confines and controls the movement of carrier 4 along rod 5. Carrier 4 likewise is positioned by the cooperation of a carrier-mounted detent and a frame-mounted rack. Drive pulley 11 is mounted for rotation in unison with gear 22. Drive pulley 21 rotates in unison with gear 23. Gears 22 and 23 are engaged to counterrotate as shaft 25 is driven by shaf...
